Standard Test Methods for Temperature Calibration of Dynamic Mechanical Analyzers

SIGNIFICANCE AND USE
5.1 Dynamic mechanical analyzers monitor changes in the viscoelastic properties of a material as a function of temperature and frequency, providing a means to quantify these changes. In most cases, the value to be assigned is the temperature of the transition (or event) under study. Therefore, the temperature axis (abscissa) of all DMA thermal curves must be accurately calibrated by adjusting the apparent temperature scale to match the actual temperature over the temperature range of interest.
SCOPE
1.1 These test methods describes the temperature calibration of dynamic mechanical analyzers (DMA) from –100°C to 300°C.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Note 10.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

4. Summary of Test Method
4.1 In dynamic mechanical analysis, often large (for example, 1 to 10 g), low thermal conductivity test specimens are
characterized while being mechanically supported using high thermal conductivity materials, while a temperature sensor is
free-floating in the atmosphere near the test specimen. Under temperature programming conditions, where the atmosphere
surrounding the test specimen is heated or cooled at rates up to 5°C/min, the temperature of the test specimen may lead or lag that
of the nearby temperature sensor. It is the purpose of this standard to calibrate the dynamic mechanical analyzer temperature sensor
so that the indicated temperature more closely approximates that of the test specimen. This is accomplished by separating the test
specimen from its mechanical supports and from the surrounding atmosphere using a low thermal conductivity material. Three test
methods of providing this separation are provided.
4.2 An equation is developed for the linear correlation of experimentally observed program or sensor temperature and the actual
melting temperature for known melting reference materials. This is accomplished by loadingin Method A by a melting point
reference materials loaded into a polymer tube, or wrapping them in Method B by wrapping the calibration material with polymer
tape and subjecting it or in Method C by placing the calibration material between glass or ceramic plates and subjecting this test
specimen to a mechanical oscillation at either fixed or resonant frequency. The extrapolated onset of melting is identified by a rapid
decrease in the ordinate signal (the apparent storage modulus, stress, inverse strain or probe position). This onset is used for
temperature calibration with two melting point reference materials.
